In Sussex County, Delaware, officers now have a handheld AI scanner that can turn a shell casing on the pavement into an investigative lead before the crime scene tape even comes down. The tool shifts microscopic toolmark analysis out of far-off forensic labs and into patrol cars, giving detectives a shot at jump-starting cases while witnesses are still around and potential suspects are still nearby.
As reported by CBS News Chicago, the device, called ShotOptix and built by Revelen.ai, was demonstrated by company cofounder Robert Poole, who said officers can learn to use it in minutes. Lewes Police Chief Tom Spell told CBS that his officers typically see results in about 10 to 15 minutes and called the system “a no‑brainer” for small agencies trying to keep up. The company says the scanner links to a smartphone and runs a rapid correlation so investigators can start following up almost immediately.
How the scanner works
According to Revelen.ai, ShotOptix pairs a compact 3D scanner with a smartphone to capture highly detailed images of cartridge casings, then sends them through a machine learning correlation engine that searches for matching toolmarks across a shared network. The company labels the process “Rapid Casing Analysis” and says it can generate high‑confidence leads in minutes while leaving the physical evidence untouched for full forensic work later. Revelen markets the device as a way for smaller departments to get near‑real‑time ballistics intelligence without waiting on traditional lab timelines.
Where it's rolling out
The technology has started to crop up in scattered jurisdictions around the country and was deployed countywide across Sussex County in mid‑May, covering 19 participating departments from Lewes to Rehoboth Beach, according to a Business Wire release announcing the program. Revelen previously publicized a deployment with the Laurel Police Department in October 2025, and vendor materials say the platform is built to scale from single small towns to larger agencies. County chiefs say the shared network means a casing scanned in one town instantly becomes a potential lead for every department plugged into the system.
Standards and limits
Federal guidance still centers on lab‑based workflows. ATF minimum operating standards for NIBIN sites recognize a 24‑ to 48‑hour target for starting ballistic acquisitions, according to PubMed Central. As CBS News Chicago noted, Revelen and police leaders present the on‑scene scans as a way to generate investigative leads while licensed toolmark examiners later handle formal confirmation. Departments say that two‑step setup is how they plan to protect chain of custody and limit evidentiary risk.
Accuracy, courtroom risk and oversight
Forensic pattern evidence, including firearm and toolmark comparisons, has been under heavy scientific scrutiny, and major reviews have flagged nontrivial error rates and limits on broad claims of uniqueness, according to the Reference Manual on Scientific Evidence. Courts in some cases have restricted how examiners can describe matches and have pointed to studies showing error rates that argue for caution when leaning too hard on automated comparisons. Those findings suggest defense attorneys and judges will likely probe validation data and disclosure practices if agencies start relying heavily on automated correlations without independent verification.
What comes next
Police leaders say the field tool could act as a force‑multiplier for underresourced agencies, helping them pull in actionable leads faster and connect related cases across city and county lines, as trade publications and industry coverage have reported. At the same time, pushing analysis to the curbside comes with tradeoffs: faster leads versus the need for careful validation, training, and oversight before automated matches turn into a regular courtroom feature. For now, chiefs in Sussex County say ShotOptix is speeding up their investigations, while established laboratory protocols still have the last word on what ultimately counts as evidence.
